An update timestamp, in the right-hand side of the menu bar, displays the last time or date Workspace data was calculated for the account. How often the data for an account is synced is determined based on your needs.
If the data was last updated today, the update timestamp displays the time the update occurred in hh:mm am/pm format. If the data was last updated at least one day prior to today, the update timestamp displays the date the update occurred in your locale's specific date format.
